DESCRIPTION
The DMW series of DC/DC converters provide up to 15 watts in a 2 x 1 x 0.4 inch package. These converters operate over 4:1 wide input voltage ranges of 9-36VDC
and 18-75VDC. This series also has single and dual output models available. These converters feature efficiency up to 86%, positive remote ON/OFF (optional),
six-sided shielding, 1500VDC isolation, and short circuit protection. This series is ideal for data communication equipment, mobile battery driven equipment,
process/machine control equipment, telecommunication equipment, computer peripheral systems, distributed power systems, mixed analog/digital subsystems, and
industrial robot systems. The EN55022 Class A conducted noise compliance minimizes design time, cost, and eliminates the need for external filter components.
SPECIFICATIONS: DMW Ultra Wide Series
All specifications are based on 25°C, Nominal Input Voltage, and Maximum Output Current unless otherwise noted.
We reserve the right to change specifications based on technological advances.
